Gallus Screeny – Metallic Doming 

"Metallic doming" describes a new and unique effect in narrow-web label printing – a reflective, metallic raised structure manufactured using a relief in rotary screen printing. What makes metallic doming unique is the lasting metal-relief effect achieved on paper or plastic film, such as tube laminates or transparent self-adhesive material.

Truly unique

The metallic doming method uses rotary printing to apply the printed image. A metallic foil is then laminated over the relief. What’s special about this process is that it allows printed images with lasting metallic reliefs to be produced on plastic. So far, it is the only procedure on the label market that makes it possible to create embossing effects on plastic. With the exception of hot foil embossing without lasting relief effects, plastic cannot be embossed as other materials can. Metallic doming fills this technological gap in the application market.

The application process in detail

During "metallic doming", a thermoreactive glue is applied using screen printing with Gallus Screeny DY, for example, and then dried with UV light. After that, the applied print image is laminated with a thermoactive, metallic foil. A soft, heated laminating cylinder presses the foil onto the glue. The foil wraps around the glue and, together with the glue, is heated by the laminating cylinder. This laminating process reactivates the glue and activates the foil.


This thermal activation means the foil sticks to the glue. After this, the printed image cools to reveal a metallic relief effect – this is the "metallic doming effect".
